The origin of life is still one of humankind's great mysteries. At the transition between
nonliving and living matter, protocells, initially featureless aggregates of abiotic matter, gain …

The isotopic composition of meteorites and terrestrial planets holds important clues about
the earliest history of the Solar System and the processes of planet formation. Recent work …

Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

The isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC)
meteorites indicates that meteorite parent bodies derive from two genetically distinct …

The timing of delivery and the types of body that contributed volatiles to the terrestrial planets
remain highly debated,. For example, it is unknown if differentiated bodies, such as that …

Nitrogen, carbon, hydrogen and sulfur are essential elements for life and comprise about 1%
of terrestrial planet masses. These elements dominate planetary surfaces due to their …

Many studies exist on magmatic volatiles (H, C, N, F, S, Cl) in and on the Moon, within the
last several years, that have cast into question the post-Apollo view of lunar formation, the …
